Fig. 4. Overexpression of 4R tau decreases the voltage-gated K+-current density but not conductance.

A Statistics for the amplitude of K+-current (IK) measured at 30 mV (upper bars) and 80 mV (lower bars) in isogenic control (wt tau) and MAPT IVS10+16 neurons. Boxes show median values; ***p < 0.001 (nonparametric Mann–Whitney test). The number of tested cells indicated. B. I–V relationship for the IK density in the isogenic control (wt tau) and the MAPT IVS10+16 cohorts. C. Conductance–voltage relationships of IK recorded in wt tau and MAPT IVS10+16 neurons. Conductance was normalized to the maximal IK conductance; lines are Boltzmann fitting.
